Product Description

Magnesium oxide with high quality cas 1309-48-4

Product description:

Magnesium oxide is commonly known as bitter soil, also known as magnesia.
Is a typical alkali soil metal oxide, chemical formula MgO.
White powder, melting point 2852 ℃, boiling point is 3600 ℃, the relative density of 3.58 (25 ℃).
Soluble in acids and ammonium salts.Slowly react with water to form magnesium hydroxide.
It can be dissolved in carbon dioxide aqueous solution to form magnesium bicarbonate.
In the air can gradually absorb water and carbon dioxide, heating emit irritating smoke.
Magnesite (MgCO3), dolomite (MgCO3·CaCO3) and seawater are the main raw materials for the production of

magnesium oxide.Magnesium oxide is obtained by thermal decomposition of magnesite or dolomite.
Magnesium hydroxide precipitation was obtained by treating seawater with lime

and magnesium hydroxide precipitation was obtained by burning magnesium hydroxide.

Magnesium oxide Application:

1, lightweight magnesium oxide is used in ceramics, enamel, refractory crucible, firebrick,

 also used as a polishing agent, binder, paint and paper filler, neoprene promoter, activator.
Medicine used as an antacid agent, laxative agent, for gastric acid and duodenal ulcer disease, 

but also used in glass dyestuff, phenolic aldehyde, plastic and other industries.

2, dead burned magnesia is magnesia, granule and brick, widely used in steel furnace, 

cement kiln, glass burner and other refractories.

3, basic granular refractories, mainly used in the metal refining industry, with block refractories as the furnace, 

or granular as maintenance materials, with spray, coating method attached to the furnace wall,

 to strengthen the fire resistance of the furnace.

production method of Magnesium oxide

1, The technological conditions controlled by each process of soda method 

are as follows: 1. Ingredients; 2. Reaction; 3. Washing; 4. Pyrolysis; 5. Pressure filtration; 6. Roasting; 7.
The production of light magnesium carbonate or light magnesium oxide by 

soda method has mature technology and high quality.
But to consume soda ash, fresh water consumption is also large.

2.The raw materials of carbamide method are high concentration bittern,

 dense bittern or high temperature salt leaching solution.
The carbon ammonia used is carbonated ammonia, carbonized ammonia water or directly

 into the brine ammonia and carbon dioxide gas, 

carbon ammonia instead of soda and brine magnesium chloride or magnesium sulfate reaction,

 the formation of the corresponding magnesium carbonate.

Storage condition :Store in a cool, dry warehouse.The packing must be sealed and moisture-proof.
It shall not be stored and transported together with organic matter and sulfur.
Avoid rain and hot sun during transportation.Handle with care during loading and unloading.

In case of fire, water, sand and all kinds of fire extinguishers can be used, 

but the aqueous solution should be prevented from flowing to flammable goods.
